Pls enlighten the utility and application of said Low density fuel, rather than developing just high energy fuel.

Its a higher specific impulse, more thrust albeit with tankage penality. But here also they are switching to composite case which in turn means weight reduction too.
Arianeôs last stage uses low density LH2 fuel, Saturn-5 used the same on its upper stage, so is space shuttle. Not only that, just think why GSLV also uses low density fuel for its last stage.
High density fuel may not be imperative for the last stage which has less to worry about gravitation drag than on a boost phase.
The article is 8 days old as published (website), yet without any rectification/correction.
If it were high density propellants, as is common - they would not be using an adjective preferably.......

third stage will be added, preferably
with low-density energetic propellants in
composite case for the range gain
